Industrial Applications of Diethyl adipate
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Plasticizer for polyvinyl chloride (PVC) | Used as a secondary plasticizer in combination with phthalate esters for processing PVC films, artificial leather, and other products to enhance low-temperature flexibility and resistance to migration |
| Coatings Industry | Solvent and flow-control additive for nitrocellulose and acrylic coatings | Employed as a high-boiling-point solvent in coating formulations to regulate evaporation rate and improve film leveling and gloss |
| Fragrance Industry | Fixative and fragrance formulation component | Applied in soap and detergent fragrances to impart fruity and floral notes and extend fragrance longevity |
| Organic Synthesis | Intermediate for organic synthesis | Participates in transesterification, hydrolysis, and reduction reactions for the production of adipic acid derivatives, polymer monomers, and pharmaceutical intermediates |
Manufacturing Quality Control of Diethyl adipate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under specified chromatographic conditions. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of free carboxylic acid groups using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Water Content | Karl Fischer Titration | Electrochemical titration quantifying water via iodine-sulfur dioxide reaction in a methanol-based reagent system. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Measurement of yellowness intensity by comparing sample absorbance or visual appearance to APHA platinum-cobalt standards. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Determination of mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Measurement of light bending angle at air-sample interface to determine refractive index as a function of molecular density and purity. |
| Residue on Evaporation | Gravimetric Analysis | Weighing non-volatile residue remaining after controlled evaporation of a known sample mass under specified temperature and time. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using flame or graphite furnace AAS with lead-specific hollow cathode lamp. |
| Iron (Fe) Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element detection of dissolved iron after acid digestion, based on characteristic atomic emission lines. |
| Chloride Content | Potentiometric Titration with AgNO3 | Precipitation titration using silver nitrate, detecting endpoint via silver ion-selective electrode potential change. |
| Ester Content (by saponification value) | Back Titration after Saponification | Hydrolysis with excess KOH, followed by titration of unreacted alkali with HCl to calculate ester group concentration. |
| Non-Volatile Residues (on filter) | Filterable Residue Gravimetry | Filtration through a pre-weighed membrane filter, drying, and weighing to determine insoluble particulate matter. |
